Total interest value on financing = 6,525 JOD, plus 3% sales tax
The value of import stamps on the contract = 45 JOD

2. How is the effective interest rate (EIR) calculated for financing?
The effective interest rate is calculated according to the following equation (EIR) = 1-12(IRR+1)
The internal rate of return (IRR) is calculated using Microsoft Excel using the IRR equation according to the following:
In the Value field: we enter all cash flows (negative and positive)
In the Guess field: (represents the expected return): enter “zero”.
The result is =0.02812
3. Which expresses the monthly effective rate.
The effective interest rate (EIR) is calculated by substituting the internal rate of return (IRR) into the following equation:
Effective interest rate = 1-12(IRR+1)
Effective interest rate = 18.312%
